    GPRXP conversion Vent system.

    The first two GPRXP's were hooked up with both in and out vents located to outside of hull. There have been a few strange issues with fouled plugs, overflowing oil vent bottle with lots of white gas/water/oil liquid. Oil purity being diluted within 10 hours. Finally, after the Vigilante sat idle for a while, it stopped running. I set Jerry's gprxp up using the stock gpr system, so his is uneffected.

    Upon inspection, water was found on the plugs, as well as a white deposition on the plugs. Water was found in the gas tank. After 15 gallons were removed, nearly a half a quart of water was poured off the bottom of the tank.

    Root cause: the vent system "in-valve" was sucking in both moisture as well as outside water. Upon dissasembly, water poured out of the vent system.
